    Generate a structured prism 3D mesh

    Parameters
    ----------
    nx : int
      Number of cells in x-direction.

    ny : int
      Number of cells in y-direction.

    nz : int
      Number of cells in z-direction.

    periodic_x: bool
      If True, the left and right boundaries are identified to generate a periodic mesh in x-direction.

    periodic_y: bool
      If True, the top and bottom boundaries are identified to generate a periodic mesh in y-direction.

    periodic_z: bool
      If True, the top and bottom boundaries are identified to generate a periodic mesh in z-direction.

    mapping: lambda
      Mapping to transform the generated points. If None, the identity mapping is used.
    
    cuboid_mapping: bool
      If True, a straight geometry is assumed.


    Returns
    -------
    (ngsolve.mesh)
      Returns generated 3D NGSolve mesh consisting of only prism
